UNITED STATES FRANK L. BAILEY, OF OKMULGEE, OKLAHOMA.

GAS MIXER.

Application filed December 15, 1927. Serial No. 240,262.

The invention relates to improvements in gas mixers of a type designed to be clamped between a carbureter outlet neck and an intake manitohl, and it the object of the invention to provide a device of this class which is extremely simple and inexpensive, yet will be unusually efiicient, permitting no gas to pass without contact with pitched, gasrrhirling vanes which cyclonically whirl the gas and thus insure the formation of a homogeneous mixture before passage to the engine cylinders.

lVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, (lescrip n being ac com plished by reference to the accompanying drawing.

1 is a longitudinal sectional view through adjacei'it portions of a *arlmrctcr outlet neck, an intake manifold and the im' proved mixer installed between them.

Fig. 2 is a vertical sectional view on line 2 in; Fig. l, and by the line l.--l, this view illustrates the plane on which Fig. l is cut.

3 is a si dc elevation of the mixer.

Fig. 4 is an enlarged fragmentary perspeclive view.

In the drawing above briefly described. the numeral denotes a flat sheet metal plate to be clamped between the outlet neck 6 of a carluireter and an intake manifold 7 by means of the usual bolts 8, the plate being formed with slots 9 to receive said bolts. At its central portion, plate has a plurality of segmental openings 10 stamped therein, leaving a plurality of radial bars 11. l'he metal from the openings 10, forms a plurality of gas-whirling vanes 12 adapted to extend into the manitold 7 and to contact throughout at least a portion of their outer edges with said manilold. These vanes 12 are narrowed toward their free ends and at their opposite ends are inte ral with the bars 11, substantially througliout the lengths of the latter. Each ane 12 has a helical trend and is trans versely curved, with its concave side disposed toward the carburetor. Each bar 11 is provided with a longitudinal curvature corre sponding to the transverse curvature of the connected vane 12 and each of these bars is pitched transversely to an extent corresponding to the helical trend of the connected vane, so that the contiguous surfaces of the vanes and bars, merge into each other and no abrupt surfaces are presented to the gas. It is thus insured that as soon as the gas strikes the vanes, it shall be cyclonically whirled without excessive retardation and shall consequently be thoroughly mixed, to produce better results than are otherwise obtainable. on

While the exact details herein presented are preferably followed, it is obvious that within the scope of the invention as claimed, sl ightvariations may be made.

I claim: a

A gas mixer comprising a sheet .metal plate having a plurality of segmental openings stamped therein, leaving radial bars between said openings, the metal stamped from said openings forming pitched gas-whirling 7o vanes equal in number to said bars and integrally connected at one end with said bars substantially throughout the lengths of the latter, said vanes each having a helical trend and being transversely curved; said bars being each curved longitudinally in conform ity with the transverse curvature of the connected vane and being transverselypitched in conformity with the helical trend of said vane.

In testimony whereof I have hereunto atiixed my signature.

FRANK L. BAILEY.
